SULPHUR GUSSASPHALT

BETON BITUMINEUX COULE AU SOUFRE

The author describes the state of the art of a new material: gussasphalt containing sulphur. This new material presents all the already known qualities of gussasphalt but the addition of sulphur permits its manufacture at a temperature lower by approximately 100 deg C than that of traditional gussasphalt. This gain is important as regards energy consumption and flexibility of use. Its manufacture in mixing plants presents no difficulty. Applied mechanically in thin layers (2 to 3 cm), this material gives the pavement perfect imperviousness and would be suitable for correcting defects of small wave length evenness. The mastic obtained, which is very hard, could support the spreading of precoated chippings that would give the surfacing non-skid properties. Its overall cost per square meter would be comparable to that of the lowest cost techniques used in maintenance excluding surface dressings. Its use as surfacing of new pavements should not be rejected a priori. Details are given of some characteristics of this material, manufacturing tests and laying experiments. (TRRL)
