CEL 782: PAVEMENT MATERIALS AND CONSTRUCTION TECHNIQUES LABORATORY RECORDS Submission Date: 19/10/20131 Asphalt Concrete Mixture Design Submitted By: Group 1 2013CEZ8070 PRIYANSH SINGH 2013CEP2073 AAYUSH KUMAR 2013CEP2074 ANJANEYULU CHINTHIREDDY 2013CEP2080 LEEZA MALIK 2013CEP2083 … Lab Report: Solubility INTRODUCTION Purpose: Explore the relationship between temperature and solubility using a laboratory procedure. For a Newtonian fluid, the relationship between shear stress and shear rate is linear, and thus the viscosity is constant at different shear rates or shear stress. A penetrometer consisting of a needle assembly with a total weight of 100 grams and a device for releasing and locking needle in any position. Third section deals with bituminous material, which is a vital component of roadway construction. This type of conclusion can also be thought of as the sentence that answers the question “So what?”. Lab report structure. 4 and the solubility surface in Fig. The ductility test (ASTM D113) measures the distance a standard asphalt sample will stretch without breaking under a standard testing condition (5 cm/min at 25 °C). 2 to determine ΔH and ΔS from the temperature dependence of K. To see if the Hansen parameter could better explain the solubility properties of bitumen we have plotted the solubility of bitumen as listed in Ref. Research & Reports; Qualified Product List; Materials Evaluation Program; Aggregate Source Approval; Request for approval of materials; Construction Audit Tracking System ; Statistical Analysis of Materials; Record of Materials; Contact Us; About Us; Materials Lab - Bituminous Materials Testing. Asphalts tend to behave as slightly non-Newtonian fluids, especially at lower temperatures. Consistency of a bituminous material expressed as the distance in tenths of a millimeter that a standard needle vertically penetrates a sample of the material under known conditions of loading, time, and temperature. Consistency of a bituminous material expressed as the distance in tenths of a millimeter that a standard needle vertically penetrates a sample of the material under known conditions of loading, time, and temperature. Various Lab Test On Bitumen Posted in Material Testing | Email This Post | Bitumen is a mixture of organic liquids that is black, highly viscous, sticky product used for paving roads, waterproofing products (used in sealing roofs). Bitumen is a complex material with a complex response to stress. The use of trichloroethylene will most likely be banned in the near future. Hence, investigation into the use of recycled materials for the manufacture of bituminous surface courses is of great interest from an environmental point of view. There are many tests which are conducted to check the quality of bitumen. Penetration Test of Bitumen EXPERIMENT NO. Penetration test Ductility test Softening point […] An asphalt with a high flash point is more likely to have a lower hardening potential in the field. Laboratory tests of bitumens : Test for Solubility. Bitumen is defmed as an amorphous, black or dark-colored, (solid, semi-solid, or viscous) cementitious substance, composed principally of high molecular weight hydrocarbons, and soluble in carbon disulfide. In brief lab reports, the conclusion is presented at the end of the discussion, and does not have its own heading. Lab Tests on Bitumen to Check Quality Various tests are conducted on bitumen to assess its consistency, gradation, viscosity, temperature susceptibility, and safety. However, for a non-Newtonian fluid, the relationship between shear stress and shear rate is not linear, and thus the apparent viscosity will change as the shear rate or shear stress changes. After 10 Specification, Bitumen Tests, and Properties of Bitumen . The standardized procedure for this test can be found in ASTM D5 [ASTM, 2001]. Solubility of bituminous materials Slideshare uses cookies to improve functionality and performance, and to provide you with relevant advertising. Tests on Bituminous Material; Who we work for. The Cleveland Open-Cup method is used on asphalt cements or asphalts with relatively higher flash points, while the Tag Open-Cup method is used on cutback asphalts or asphalts with flash points of less than 79 °C. Videos of our milestones Read on and be guided by these steps: The Pre-Lab Report Here we’ve compiled for you a few tips to guide you from start to finish. Other test conditions that have been used include. ... • Develop Report on Solubility Background and Survey • Useful information collected to date Due to the extreme flammability of carbon disulfide, solubility in trichloroethylene, rather than solubility in carbon disulfide, is usually used in asphalt cement specifications. Lab Report of Los Angeles Abrasion Test on a Given Sample, Aggregates - Types of Aggregates | Coarse Aggregate, Fine Aggregate, Factors Affecting Selection of Construction Materials, Uses of Aggregates in Construction, Roads, Railway Ballast, Properties of Bitumen and Bituminous Materials, Gradation Of Aggregates | Types of Aggregate Grading, Chemical and Physical Composition of Bitumen, Properties of Wood & Timber - Physical & Chemical Properties of Wood, Manufacturing and Uses of Portland Cement, Artificial Methods of Wood and Timber Seasoning, SAP 2000 and ETABS Training Course on Realworld Civil Engineering Projects. 1 can be combined with Eqn. Report 6.1 A normal test is one in which the material between the two clips pulls out to a point or thread until rupture occurs at the point where the thread has practically no cross-sectional area.
