The author reviews some recent research achievements of the Highways Group at TRRL and discusses how future challenges are being met. He sees the main challenge as the need continues to give better value for money and to reduce congestion while continuing to improve standards of safety. Various aspects of the Group's work are outlined, including: (1) the development of the SCRIM (sideway-force coefficient routine investigation machine) machine used in surveying trunk roads for the new Department of Transport skid resistance standard; an estimated saving of 1800 casualties per annum gives a financial benefit of 35 m per annum for a research cost of under 10 m; (2) the experimental introduction of a more durable pervious macadam on the A38 in Staffordshire in an attempt to reduce spray, especially from heavy lorries; (3) innovative research aiming to reduce the frequency and duration of roadworks; (4) the development of the high speed road monitor (HRM), thus reducing survey disruption; (5) investigation of recycling of bituminous materials, allowing cheaper and faster replacement of road surfacing; (6) cooperative development of a new heavy duty Macadam roadbase, giving savings of up to 3 m per annum on trunk roads; (7) development of a shear-box test to allow cheaper, quicker trafficking trials on gravel sub-bases; (8) the international aspects of the group's work including cooperative projects with OECD and the United States Strategic Highway Research Program (SHRP), and (9) links to the consumer via the Local Authorities, TRRL reports, the IRRD database and the TRRL's Technology Transfer Unit.
