The economic worth of the steel retrieval by making the relevant products is very considerable, and so it causes a lot of thieves and some people who had little covetous psychology to have the stealing and selling behavior. It also causes the ditch cover made by cast iron to be stolen and jeopardize passersby and traffic safety. This research was focused in the further improvement shortcoming (including weight, unit price, and loading) of general ditch cover. The test parameters included the steel fiber content, the hole number and the thickness of ditch cover. To study the performance of reactive powder concrete on ditch cover, the 8 holes and 12 holes modeling test and the welded wire mesh were applied. The main process of experiment was in search of the ditch cover which enough bears heavy vehicle weight. The test load standard is 10 tons for the ditch cover that is the heavy vehicle average allocation with every tire in the experiment consideration. This study was to find the RPC ditch cover and also to compare with the casting iron ditch cover, the zinc grid ditch cover and glass fibre high polymer compound ditch cover on the market. The results show that adds 3% volume content of steel fibre, steel welded wire mesh and the 8 holes RPC ditch cover, the loading has already reached to the weight of all kinds of heavy vehicles. The results have also found out the suitable proportions of RPC for making the ditch cover.
