New products and the development of thin surfacing materials for poland

Develop innovative highway processes for poland comprising
four principal stages: testing of new bitumen formulations;
asphalt design and properties; field validation in road
trials; plant design, construction and commissioning.

There is a need to develop innovative road designs which will meet tomorrow's traffic demands while remaining cost effective. A thin surfacing concept is proposed which will address both the increased bearing capacity of the highway network and offer cost effective measures within constrained highway budgets. In particular, the concept of thin surfacing road materials is likely to gain in popularity because the processes seek to combine the minimising of resources with the maintaining of satisfactory road performance. Consideration will be given to pavement durability and road user safety and also to environmental issues (for example noise reduction). This project will focus on the development of new thin surfacing road materials, taking into account the specific requirements for the Polish market. The project will comprise four principal stages: Stage 1 Binder selection and testing. Bitumen properties are very important in determining the performance of asphalt materials . A number of bitumens, some modified, will be selected at the initial stage. Some of these binders will be new formulations based on Polish supplied bitumens. One (or two) unmodified bitumens will be used as controls. This stage will consider binder development as well as testing. The testing will be to verify that the binders selected will meet the current Polish specifications. Test methods will include both empirical and fundamental measurements. It is expected that from this stage a number of suitable binders for thin surfacing materials will be identified. Research will be carried out by both BRITISH PETROLEUM and INSTYTUT BADAWCZY DROG I MOSTOW. Stage 2 Asphalt mix design and material properties. A number of different asphalt mix designs (minimum of three) will be proposed using Polish aggregates and gradings. The designs selected will take into consideration the local requirements. The promising binders from Stage 1 will be examined in the laboratory mixes which will involve measuring the physical properties of fatigue, creep and deformation resistance. At the completion of this stage, it should be possible to quantify the benefits of both the thin surfacing concept and the use of modified binders. Research will be carried out by BRITISH PETROLEUM and INSTYTUT BADAWCZY DROG I MOSTOW. Stage 3 Road trials. Road trials will be carried out on the Polish highway network to validate the results on laboratory mixes. The trials will assess the laying characteristics and subsequent in-service performance. Monitoring of the innovative surfacings will be carried out and will include measurements of evenness, texture, skidding resistance and noise reduction together with a structural and visual assessment. Stage 4 Plant design, construction and commissioning. Having identified suitable binder formulations for thin surfacing applications, BRITISH PETROLEUM intends to design and construct a local manufacturing facility (or facilities) to market the speciality products. The design will be innovative in that special blending and shearing techniques may need to be used. The process will involve: a statement of requirements, plant design, identifying partners and site location(s), construction, commissioning and operator training.
