The soil has an important role in construction, namely as the loading of soil on clay. It is necessary to improve the nature of the shrinkage. The authors conducted the study to increase the strength of clay by adding wood ashes and bamboo ashes. Wood ash and bamboo ash have pozzolan properties expected to add power to clay when weighted, would drop significantly.  Material compares in this study using a mix of wood ash and bamboo ash with a variation of 0%, 4%, 8%, and 12%. Meanwhile, the clay soil is taken directly from the ravaged area, from bulging villages, from the grid district. The results showed that the soil is categorized as montmorillonite soil with properties that can damage light structures and road surface runoff. After adding wood and bamboo ash, it showed optimum results of 12% of the dry fixed test items showing a liquid limit’s value at 41,00%, plastic limit at 28,43%, and the net value of plastic limit at 12,57%. When testing for solidification using native soil at a dry volume of 7,91, gr/cm rainfall can increase by 10,42 gr/cm additives after adding 12% of wood ash and bamboo ash.Tanah memiliki peran penting dalam konstruksi yaitu sebagai pembebanan tanah pada tanah liat. Perlu untuk memperbaiki sifat penyusutan. Penulis melakukan penelitian untuk meningkatkan kekuatan tanah liat dengan cara menambahkan abu kayu dan abu bambu. Abu kayu dan abu bambu memiliki sifat pozzolan yang diharapkan dapat menambah kekuatan pada tanah liat saat tertimbang, akan turun secara signifikan. Perbandingan material dalam penelitian ini menggunakan campuran abu kayu dan abu bambu dengan variasi 0%, 4%, 8%, dan 12%. Sementara itu, tanah lempung diambil langsung dari area yang rusak, dari desa-desa yang menggembung, dari grid distrik. Hasil penelitian menunjukkan bahwa tanah tersebut dikategorikan sebagai tanah montmorillonite dengan sifat yang dapat merusak struktur ringan dan aliran permukaan jalan. Setelah dilakukan penambahan abu kayu dan bambu didapatkan hasil optimum dari 12% benda uji tetap kering yang menunjukkan nilai batas cair 41,00%, batas plastis  28,43%,   dan   nilai   bersih   batas  plastis  12,57%.   Pada pengujian solidifikasi menggunakan tanah asli pada volume kering 7,91 gr / cm curah hujan dapat meningkat sebesar 10,42 gr / cm aditif setelah penambahan 12% abu kayu dan abu bambu.

Introduction. The current state and the development of road construction and infrastructure is the cause of increasing the environmental pollution, especially in close proximity to the roads.Problem Statement. Surface runoff from the roads is a significant volume of polluted water which most often enters water bodies and the surrounding area without treatment, which is contrary to environmental requirements. Not only accidental leaks of oil and chloride residues present in runoff, but also a significant volume of suspended solids, which are often settled and accumulated and are dangerous for the environment and public health. In order to predict measures or prevent such pollution and accumulation, it is necessary to determine the sources of suspended solids, qualitative characteristics, physical and chemical properties of pollutants.Purpose. The purpose of the work is to determine of suspended solids pollutants (micropollutants), their components, to develop a classification of sources and their formation.Materials and methods. Analytical, information retrieval methods were used for this study.Results. As a result of the work, classification, which presents potentially possible types of micropollutants which are the components of suspended solids found in road surface runoff, was developed.Conclusions. The developed classification of micropollutants sources is the initial stage to study such kind of pollution, migration in the environment, the impacts of accumulation and decomposition products, as well as to develop measures for reducing the formation and dissemination of micropollutants in the environment.Keywords: road pavement, micropollutants, composition, particles.

Abstract This is a summary of work by the author and his colleagues, as well as by others reported in the literature, that demonstrate a need for considering a vehicle, its tires, and the road surface as a system. The central theme is interaction at the footprint, especially that of truck tires. Individual and interactive effects of road and tires are considered under the major topics of road aggregate (macroscopic and microscopic properties), development of a novel road surface, safety, noise, rolling resistance, riding comfort, water drainage by both road and tire, development of tire tread compounds and a proving ground, and influence of tire wear on wet traction. A general conclusion is that road surfaces have both the major effect and the greater potential for improvement.
