Abstract:

The UK Highways Agency and the National Salt Spreading Research Group (NSSRG) commissioned Transportation Research Laboratory (TRL) Limited to evaluate the applicability and costs of introducing prewetted salt on both the motorway and all-purpose trunk road network and local road network in England and to verify the claims made by users and salt suppliers about prewetted salting technologies. The project work is in two stages: (1) a report on the use and effectiveness of prewetted salt and the environmental issues, costs, benefits, and safety issues associated with the use of prewetted salt technologies and (2) design, implementation, monitoring, and reporting of comprehensive tests on the research track at TRL and on in-service motorways. Performance trials and road trials have enabled direct comparisons to be made between dry salting techniques and prewetted salting techniques. The rate at which undissolved salt grains enter into solution is being monitored together with the amount of salt reaching the target area, the optimum grain size of salt, the wastage to the roadside shoulder, and longitudinal snaking. The trials and the results have enabled the efficiency of the two salt systems to be better understood for both symmetric and asymmetric spreading and the distribution of salt on the carriageway to be quantified for different spreaders and salts. The results of these trials should provide the UK Highways Agency and NSSRG with evidence on which to base a decision concerning the use of prewetted salt on their road networks. Further information from a cost-benefit analysis would enable an informed decision to be made as to whether a change to prewetted salt is justified in economic terms.
