WebStandard Method of Test for Coating and Stripping of Bitumen-Aggregate Mixtures inactive Buy Now Details History References scope: This method describes coating and static immersion procedures for determining the retention of a bituminous film on an aggregate surface in the presence of water. WebDec 13, 2024 · For this purpose, 13 laboratories conducted a round robin test on affinity between aggregates and bituminous binders in presence of water. Three methods—rolling bottle test, boiling water stripping test and bitumen bond strength test—were used with four different aggregate types and three bituminous binders.

WebIn order to verify whether the aggregate stripping force obtained via simulation can meet the requirements of the force required for actual asphalt stripping, the WDM-100 electronic universal testing machine was applied to conduct a single particle asphalt-stripping test, as shown in Figure 9a. The aggregate and RAP were, respectively, fixed to ... WebThe authors' conclusions are that: (i) the test for stripping as per Indian Standard is inadequate; (ii) the ten minutes boiling test appears to be a quick and efficient test for studying susceptibility of the aggregates to stripping; (iii) slaked lime is found to be a good antistripping material; (iv) open graded bituminous mixes strip badly ... todd shupp university of kentucky

WebIn general, aggregates that are hydrophilic (attract water) are more likely to strip than aggregates that are hydrophobic (repulse water). To address this, either stripping-susceptible aggregates can be avoided or an anti-stripping asphalt binder … WebNov 25, 2016 · Anti-stripping agents are chemical mixtures containing active functional groups that improve the adhesion of the bitumen film on the surface of the aggregates. Mixed with the binder, they lower the surface tension of the bitumen (figures 2 and 3). There are different types of anti-stripping (amino, polyphosphoric or silane). WebFurther, the presence of water causes stripping of binder from the coated aggregates. These problems occur when the bitumen mixture is permeable to water.
