Ta? mastik asfalt?n agregalar aras? bo?luk oran?n?n fazla olmas? nedeniyle yüksek oranda ba?lay?c? gerektirmesi, bitümün agregalardan süzülmesine neden olmaktad?r. Süzülmeleri engellemek için kullan?lan geleneksel elyaflar?n (mineral, selüloz) pahal? olmas?ndan dolay? kaplama maliyetleri artmaktad?r. Bu çal??mada selüloz yerine tekstil fabrikalar?nda at?k olarak nitelendirilen at???n?n kullan?m...

Reclaimed asphalt pavement (RAP) arises from the demolition of road layers. The Optimal Recycling Asphalt Pavements Project concerns cold recycling 100 % RAP without binder addition in base and subbase layers low-traffic roads. In this context, a test program was performed with Rhine region materials to evaluate impact mastic coating untreated RAP. A source reclaimed asphalts 4.4 bitumen is tes...

Using a multifactorial experiment of the plan N = 2(4), influence components air pollution in livestock buildings on moisture absorption film D-11A plastisol mastic was studied by gravimetric method. The corresponding dependence equations are obtained, which show more aggressive effect hydrogen sulfide and sulfur dioxide protective film.

Objective: One complication of fixed orthodontic treatment in patients with poor oral hygiene is development of demineralized enamel lesions compromising esthetics. This study aimed to review preventive measures and treatment of white spot lesions (WSLs) in patients with fixed orthodontic appliances. Review of Literature: In this review study, PubMed and Google Scholar databases were searched f...

INTRODUCTION An industrial hygiene database has been constructed for the exposure assessment in a study of cancer risk among asphalt workers. AIM To create models of bitumen and polycyclic aromatic hydrocarbons (PAH) exposure intensity among paving workers. METHODS Individual exposure measurements from pavers (N = 1581) were collected from 8 countries. Correlation patterns between exposure ...
