THE USE OF WASTE AND LOW-GRADE MATERIALS IN ROAD CONSTRUCTION: 5. CHINA CLAY SAND

This report describes an investigation to establish the potentialities for road construction of the sands from China clay workings. The main outlet for the sand in road construction is a bulk fill, but sand of the correct grading for granular sub-base can be obtained and it can be readily stabilised with cement to meet the requirements for cement-bound granular materials. The sand can also find uses, although in much smaller amounts, in concrete, bituminous mixes and in a synthetic aggregate with high resistance to skidding. It is concluded that the sand has a high potential as a roadmaking material. The major factor inhibiting its increased use is its location in an area where relatively little road construction is planned; the high cost of haulage to areas where a demand exists thus limits its value. /Author/TRRL/
