Abstract:

This paper describes the properties of bitumen bound macadam (BBM) and compares its performance with that of water bound macadam (WBM) and BUSG, a specification used by the Indian Ministry of Surface Transport. The BBM advantages of the BBM method include: (1) rapid construction; (2) less disturbance to traffic; and (3) relatively low cost. It has already been used successfully at several sites in India. BBM is similar to WBM, except that key aggregates and bitumen are used as binder, instead of screenings and water. The BBM layer can conventionally be laid over an existing bitumen layer, after applying a tack coat. The construction techniques for a layer of BBM are like those for a layer of WBM. BBM was found to be a suitable alternative treatment to WBM and BUSG, and it has a relatively dustproof surface. When overlaid by a hot mix paver treatment, a BBM layer has still better performance and riding conditions. It is predicted that precoating of 12mm size aggregates, in future forms of BBM, will improve the performance of the top layer, and reduce metal 'fly-off' due to traffic. One appendix gives the specification of BBM; the other compares the specifications for BBM, WBM and BUSG.
