PERFORMANCE AND DURABILITY OF BITUMINOUS MATERIALS. 13: PERFORMANCE ASSESSMENT OF SPANISH AND BRITISH POROUS ASPHALTS

摘要: Porous asphalt is currently gaining in prominence the UK after recent legislation that will help enhancing its use to a level comparable other European countries. In Spain, porous has been used extensively and well established performance record. The material predominantly designed with aid of Cantabro Test, developed originally at University Cantabria based on abrasion loss undergone by specimens being rattled Los Angeles machine without steel balls. UK, apart from Binder Drainage Test propounded Transport Research Laboratory which conducted uncompacted mix specimens, there no laboratory tool can be design. This paper attempts arrive design method takes into account parameters referred above address limitations asphalt, namely strength, porosity durability. Non destructive tests for determination elastic modulus permeability have proposed make maximum prepared samples before introducing them Cantabro-like test determination. grading specifications BS 4987 adopted according method. these mixes was then compared Spanish inferences made thereof. Recommendations further refinement also made. (A) For covering abstract see IRRD 875331.
