Investigação sobre a formulação de um bio-ligante à base da seiva de Euphorbia ...
Gondim, Lilian MedeirosThe present study aims to contribute to the development of a binder for use in pavement layers, from the modification or partial replacement of the asphalt binder by the sap of Euphorbia Tirucalli (Petroleum Plant). For this purpose, bio-binders were produced from the addition of the sap to an asphalt binder classified by penetration as 50/70 (PG 64-22) in the contents of 3% to 30%. The parameters investigated ...
Petroleum plant sap as an asphalt modifier for pavement applications
Gondim, Lilian Medeiros; Soares, Sandra de Aguiar; Barroso, Suelly Helena de AraújoThis research work aims to contribute to the development of a bio-binder for use at the paving industry, from the modification of a petroleum based asphalt by the sap of Euphorbia Tirucalli (Petroleum Plant). Thus, a base asphalt (PG 64-28) was modified with 3%, 5% e 10%, by weight, of sap of the petroleum plant. The functional groups present in the sap were characterized by Fourier Transformed Infrared Spectro...

Gondim, Lilian MedeirosTaking into account that the agribusiness of Baixo Jaguaribe’s Agricultural Pole is developing again, it is essential to improve the road network of the area. However, the low traffic volume observed in the local highways, the low quality of the materials in the area and the limited available resources to invest on infrastructure make the road constructions economically unfeasible. Therefore, it became necessar...
