adding of vermiculite aggregates in asphalt road

Vermiculite Concrete

Vermiculite Concrete Introduction Vermiculite concrete is a low density nonstructural construction product It is insulating (both thermally and acoustically) and intrinsically fire resistant It is normally made simply by mixing exfoliated vermiculite as the aggregate, with cement and water, plus additives such as plasticisers if requiredAdding thermal resistance aggregates into the asphalt mixture would cause the residual Marshall stability and TSR of asphalt mixture to decrease, to a certain extent Surface treatment of thermal resistance aggregates could significantly improve the water stability of thermal resistance asphalt mixturesUtilization and properties of road thermal resistance

Characterization of stripping properties of stone material

Aggregates and bitumen together form a composite called asphalt concrete pavement Moisture damage to asphalt concrete pavement can occur as stripping, and is a common problem that can lead to costly repairs There is therefore a need to understand which stone aggregates adhere best to bituminous binder and result in a minimum of stripping Lifshitz used the refractive index to estimate theIn order to compare the fatigue performance of different asphalt mixtures, indirect tensile fatigue test was carried out according to EN1269724E as shown in Fig 3The weighed aggregates, asphalt and mineral powder were poured to BH20 fully automatic asphalt mixture mixer which has been preheated for more than 1 h, and then stirred for 3 minEffect of multiscale nanocomposites on performance of
