Hot mixes

WETFIX BE is a liquid additive specially designed for hot asphalt where good thermal stability is required. WETFIX BE can be stored in hot bitumen for up to 5 days at temperatures up to 170 ° C, without significant loss of efficiency. It is based on steps or soft cuts. Adhesion enhancer and coating aid for cold mix of foamy asphalt. Versatile adhesion promoter suitable for a wide variety of applications, including soft bitumen mixes. Type of bitumen and aggregate used in the dosage of WETFIX BE. It is normally added to the binder between 0.2% and 0.5%. Wetfix BE is a versatile adhesive agent for use as bitumen, road oil and reducing binders with the advantages of thermal stability, liquidity and low volatility. However, the stability of Wetfix BE when hot depends on the acid number of the bitumen and the temperature of the bitumen. Requirements relating to the properties of bituminous binders are laid down in European standards. The physico-chemical behavior of bitumen depends on its colloidal structure (asphaltenes dispersed in an oily matrix formed of saturated oils, aromatics and resins, which depend mainly on its raw source and its processing). The properties of bitumen are evaluated by group composition, fundamental analysis, but more often conventional or functional tests. For road uses, bitumen is evaluated on the basis of its physical properties. In order to improve the qualitative properties of bitumen and asphalts, additives, for example. increase its elasticity, increase thermal stability, increase adhesion to aggregation, decrease viscosity, increase aging resistance, prevent drainage of binder from aggregate surface, etc. The aim of the presentation is to evaluate and compare the effect of additives on their properties. bituminous binders. In the paper, the results of bitumen properties, penetration, softening point and dynamic viscosity of bitumen 35/50, 50/70 and polymer-modified bitumen PmB 45 / 80-75 were investigated. Application of selected additives (Sasobit, Licomont BS100, Wetfix BE and CWM) to improve adhesion to the aggregate and improve handling. The measurements of the goods were carried out according to the European standards in force. Laboratory tests have shown that pavement grade bitumen 50/70 and 35/50 greatly increases the softening point between 13 and 45 ° C. The effect of various additives on the softening point of bitumen is different. The penetration depends on the type of bitumen and the additive used. The penetration values ​​of the bitumen PmB 45 / 80-75 modified with the additives Sasobit and Licomont BS100 show an increase in the hardness of the bitumen of 16 0.1 mm and a slip in the transition. When calculating as a temperature sensitivity parameter in the penetration index, changes in penetration and softening points are indicated significantly. The additives changed the viscosity of the bitumen to lower values, mainly with modified bitumen. The viscosity increases in the case of the Wetfix BE mixture mixed with the additive in a ratio of 35/50. The additive modifies the properties of the binders original bituminous material, which can affect the properties of asphalt mixes and asphalt layers.
Advantages and features
-Versatile Product: Wetfix BE offers both active and passive adhesion and is used in a wide variety of asphalt mixes and spray applications.
In addition to the above surfactants, various adhesion promoters were also selected to study their effect on the coagulation of bitumen on a mineral substrate in the presence of water. These additives were Diamine OLBS (for active adhesion), WetFix BE and WetFix N (for active and passive adhesion).

Sigma-Aldrich anhydrous CaCl2 with reagent plus grade was also used in this study. Hydrochloric acid (HCl) and sodium hydroxide (NaOH) were used to control the pH of the soap solution.

4. Results and discussion
In the first experiments using the droplet relaxation method, the coalescence or cohesion of two bitumen droplets was studied with different surfactants in the aqueous phase.
4.1. Coalescence or Cohesion of Bitumen Droplets The test for coalescence or cohesion of bitumen droplets comprises two steps. First, the coalescence of the two droplets occurs when the protective barrier or the electrical double layer is penetrated.
Then there is shape relaxation of these two droplets when they merge into one. In this work, the relaxation test was carried out on a single grade of Nynas bitumen (70/100 pen) at 40 and 50 o C. The viscosity of the bitumen being very high at low temperature, the shape relaxation takes a very long time. long. time. For this reason, an intermediate temperature range was selected to perform the bitumen droplet coalescence test in an emulsion environment. In addition, the relaxation kinetics of bitumen droplets were studied in an aqueous phase containing four [(A) cationic R-tallow diamine, (B) R-tallow diamine ethoxylate, (C) R-tallow amido-amine and ( D) Large quaternary R-amine], one [(E) R-tallow ethoxylated nonionic alcohol], and two anionic (amphoteric) emulsifiers [(F) amine based amine of the type glycinate, and (G) R-tallow-ampho-poly-carboxy-glycinate] emulsifiers.

The results of the droplet coalescence test in an aqueous phase with selected compositions containing emulsifiers and salt are shown in Figure 8. The relaxation time is increased by adding emulsifiers as well as salt to the aqueous phase. Likewise, a higher concentration of emulsifier slows down the coalescence process. A summary of the experimental results illustrating the droplet coalescence without mineral surface is given in Table 1. Table 1. Experimental results for the coalescence of bitumen droplets (Pen.70 / 100) in an aqueous phase containing selective additives (e.g. emulsifiers, salt).
Four sets of cationic amine-based emulsifiers (A to D) were tested with selected concentrations of each surfactant. It can be seen that the activity of emulsifier D is pH dependent. In most cases, for the fast and medium setting cationic emulsions, the pH was set between 2 and 3. The coalescence time of these emulsifiers can be compared at pH = 2.3, where emulsifiers B and D exhibit almost the same activity, although less than emulsifiers C and A, respectively. However, for slow setting cationic bitumen emulsion applications, emulsifier D is used at neutral pH. In addition, the coalescence test confirmed, as shown in Figure 9, that the bitumen droplets do not coalesce and that the relaxation kinetics are extremely slow in the case of the emulsifier D at neutral pH.

The presence of surfactants or surfactant molecules at the interface also modifies the surface tension, and their variation in concentration gives rise to surface tension gradients. In addition, the contraction or expansion of the interface can also affect the surfactant concentrations, which leads to variations in surface tension. In the early stages of coalescence, during the opening of the neck, the droplet interfaces contract and if emulsifiers are present, such interface shrinkage will increase their concentration, thereby reducing surface tension. However, if the surfactant concentrations are already high, above the critical micellar concentration (CMC), further increases (or small surface variations) will have very small effects on surface tension.
The aqueous phases illustrated in Fig. 10 also consist of soap solutions with A - D emulsifiers (Table 1).

such as certain additional emulsifiers (E - G) and certain adhesion promoters such as the diamine OLBS, WetFix N and WetFix BE. Table 2 shows the concentrations of emulsifiers selected in the aqueous phase at a given pH.
Table 2. The concentrations of emulsifiers selected in the aqueous phase at a given pH. The surface tensions of the aqueous phases containing additives were measured using the Wilhelmy plate method [23] at room temperature. It can be seen from Figure 10 that the surface tensions of the aqueous phases have changed with different functionalities of the surfactant molecules as well as the addition of salt.

The coalescence of the bitumen droplets as a function of the interfacial tensions (IFT) of the aqueous phases is shown in FIG. 11, as measured using the Wilhelmy Plate technique. The study shows a weak correlation between the coalescence kinetics of bitumen droplets and IFTs. In addition, the addition of adhesion promoters to the aqueous phase containing emulsifiers reduced the IFTs in all cases. For example, in the case of an aqueous phase containing a surfactant A (R-tallow diamine), the addition of OLBS diamine resulted in a greater decrease in IFT than the addition of WetFix N and WetFix BE. However, in the case of surfactant B (R-tallow diamine ethoxylate), the addition of OLBS diamine and WetFix BE reduced the IFT to the same level. In contrast, the addition of WetFix N produced a very small decrease in IFT. This small reduction in the IFTs of the aqueous phases due to the addition of adhesion promoters can prolong the coalescence process. However, the surface activity of these soap solutions showed a small effect on the coalescence process.Khan, Redelius, Kringos

4.2 Cohesion and adhesion of bitumen droplets
The cohesion and adhesion of the bitumen droplets were studied together. Figure 12 shows the relaxation of bitumen droplets in pure water without any additives, where the coalescence of two bitumen droplets has occurred far from the mineral surface (Fig. 12a) and flush with the surface (Fig. 12b). At the end of the experiments illustrated in Figs. 12-18, the vertical positions of the two L-shaped hooks were moved upwards to loosen the bitumen droplets from the stone surface to observe the adhesion. The results show that the relaxation times of two bitumen droplets are the same in both cases.
