During the early 1990s a number of full scale trials were constructed in Peninsular Malaysia by the Public Works Department (JKR) which were designed to establish the most cost effective method of maintaining cracked asphaltic concrete surfacings. The construction and condition of these trials has been monitored under a cooperative JKR/TRL research programme. This paper describes the performance of two of the trials based on condition measurements taken in January/February 1997.
The trial constructed on Route 5 was designed to evaluate the performance of thin bituminous overlays with various crack relieving interlayers. The trial on Route 10 was designed to compare the performance of different thin bituminous seals.
