The cost of delaying the trafficking of repairs made by cement stabilization has restricted the widespread use of the method. Tests are being carried out in East Sussex using a glass fibre reinforced surface dresssing over a cement bound layer which can be opened to light traffic immediately after laying. The high tensile strength of the glass fibre matting allows it to follow a small deformation in the sub-base without cracking. The cost of the treatment can be less than half that of conventional reconstruction using new materials. The process uses a self propelled rotorvator to pulverise a strip of the existing pavement, cement is spread on the pulverised surface at 8 per cent by volume and the mixture is rotovated again. It is then compacted by a vibratory roller. Surface dressing is then laid using a modified tanker with a glass fibre chopper at the rear to place fibres after the first coat of bitumen. A layer of 10 mm slag chippings is placed next followed by another bitumen coat and a second dressing of 6 mm chippings. (TRRL)
