Show Successful Road Repair Ideas Tried in Kansas Salvaging old pavements is an Important Im-portant factor In the work of the highway high-way engineer, and various methods have been adopted In ths different localities. lo-calities. In Kansas, C. W. Boulson, city engineer of lola, has worked out s method of salvaging concrete pavements pave-ments by resurfacing with asphalt In 1012 the city of lola laid s six-Inch cement concrete pavement on East Jackson avenus in the residential section. sec-tion. After being subjected to traffic for six months ths pavement began to show . signs of disintegration. Trans verse and . longitudinal cracks developed devel-oped and where these cracks crossed traffic gradually wore boles In ths pavement According to Mr. Boulson, the cracking crack-ing was not dns to faulty material or workmanship, but to expansion and contraction with temperature changes. It was decided that ths most economical economi-cal procedure was to overhaul the old concrete pavement and to use It as s foundation for a pavement of asphaltle concrete. All loose material wis removed re-moved from ths old pavement and all weak spots were cut out Holes which penetrated to the entire depth of ths old pavement or nearly so, were filled with new concrete Pot-holes and large boles which did not extend to the subsoil sub-soil were filled with asphaltle binder. Finally, an asphaltle concrete surface two inches thick was laid and the street immediately opened to traffic. Ths rejuvenated pavement has given excellent service. |
