"The reinforcement of forest timber hauling roads is a broad issue that includes many different solutions. All of them need to respect the fact that timber transport puts the maximum allowable pressure on the axles of the design vehicle as well as on the surface of forest roads. Also the economic aspect of the solution is emphasised as forest roads are roads with a low intensity of transport. Therefore, a suitable solution for forest road reinforcement must incorporate both of these opposing requirements. It means a forest road is to be constructed so that it is economically acceptable in direct proportion with the revenues and costs of forest management and, at the same time, meets the qualitative requirements related to the heavy use of the hauling vehicle axle. In addition, it is necessary to realise that forest stands are often located on terrain least appropriate for road construction. Some forest roads need to be operational all year round and their reinforcement design has to take this into account with a proposed surface layer that will satisfy this requirement. All in all, the construction and reinforcement of forest roads are loaded with high requirements. For this reason, besides the classical technologies of structural road layers for seasonal or all-year-round operation such as unbound mixtures and penetration macadam, other suitable technologies of reinforcement that will comply with the aforementioned requirements are sought after. One of them is fly ash suspension. This grouted constructional layer is used as a reinforcement layer for forest roads. This paper describes the development of reinforcement and construction of forest roads and provides the partial results of an experiment in which reinforcement was carried out using a fly ash concrete suspension."@en .
