COLD ON APPLICATION, HOT ON PERFORMANCE

This article discusses the problems involved in producing a cold lay macadam mix particularly for use in reinstating footways and carriageways. The need for a permanent cold lay surfacing material (PCLSM) became apparent two years ago but its development has faced a number of challenges. The PCLSM must require minimal modification to quarry plant. Secondly, the mix must meet storage and site handling requirements. It must in particular have the advantages of a cold 'deferred set' material but the performance of a hot mix. The PCLSM must also obtain formal approval. Brief details are given of trials undertaken with some of the PCLSMs that have been developed.
