A. (Andy) Anderson an- nounced today. Francis was originally con- structed of concrete without steel reinforcement. Anderson said cracks developed in the street, which making riding poor. The concrete has been broken into small pieces and awaits application of the seal coat mix. The treatment will be under the direction of Dr. Douglas Bynum of Texas Transpurtatinn Institute and Lloyd James, city engineer. U.S. Rubber Reclaiming Co. of Vicksburg, Miss., is providing the ground rubber; Texas Emulsion Co. of Austin, the emulsion; and Slurry Seal, Inc., of Waco, the equipment and construction. Anderson said the products and services are being provided gratis. C S , s ex sion��� on eet renair w ru e City officials here plan to ex- pand their experimental work in use of ground scrap rubber tires to repair cracks in streets. College Station City Engineer Lloyd James said the concept may also be broadened to include other waste products, such as plastic containers and glass. James termed the most recent test of methodology "completely successful." The ground tires were mixed with sand in an asphalt seal coat for use as a stress - relieving inter- face for cracks in unreinforced concrete in the "Carter's Grove" section of the city. James said the most recent test, on Sept. 4, was the third in a series. The two earlier attempts did not produce the desired re- suits, he noted. The concept of using old tires for surfacing streets and high- ways was conceived by Dr. Dou- glas Bynum, research engineer at A &M. In addition to use as a patch- ing material for existing streets, James plans to employ the tire mixture on a new limestone base street before applying the normal asphaltic concrete riding surface. James noted three private com- panies have participated in the experiment. They are the U. S. Rubber Reclaiming Co. in Vicks- burg, Miss., which provided the ground rubber; Texas Emulsion Co. of Austin, supplier of the emulsion, and balworth Slurry Seal Co., Inc., of Arlington, which laid the surface.
