Response of Cold Mix Asphalt Produced with Straight Run Bitumen blended with Polyethylene to Static Loading

Abstract

An alternative maintenance option for road surface repairs is the use of cold asphalt mix, which is environmentally friendly when produced with non-degradable waste pure water sachet that have assumed environmental nuisance within the rural and urban dwellings in developing nations. Consequently, the mechanical and performance characteristics for acceptability of cold mix asphalt produced from straight-run bitumen blended with dissolved waste pure water sachet were evaluated in order to ascertain the technical, engineering, environmentally and economic viability of a newly developed product for pavement maintenance. Cold mix asphalt binder was obtained by processing straight-run bitumen with chemically dissolved pure water sachet at temperature of 90oC, chemical, surfactant and water blend. This experimental cold mix asphalt was produced in a large scale with a 2m3 capacity concrete mixer at specified design mix formula of 35% coarse aggregates, 65% fine aggregate and 10% mineral filler and the optimum binder. The experimental was subjected to laboratory Marshall tests, static loadings under the typical sub-tropical weather and climate in Minna, Niger state Nigeria
