  1. CVE 409HIGHWAY ENGINEERING DR O.S ABIOLA DEPARTMENT OF CIVIL ENGINEERING UNIVERSITY OF AGRICULTURE, ABEOKUTA

  2. INTRODUCTION • Teaching approach & Grading Policy • COURSE OUTLINE • Highway Geometric Design • Route Location • Soil and Bituminous material • Traffic Engineering

  3. HIGHWAY GEOMETRIC DESIGN • Factors Influencing Highway Design Highway design is based on several design standards & controls, Which depend on; • Functional classification • Expected traffic volume and vehicle mix • Design speed • Design of the Alignment • Horizontal alignment • Vertical alignment • Super-elevation

  4. Route Location • Techniques for Highway surveys • Ground surveys • Remote sensing • Principles of Highway location • Office study: engineering, topography, geology etc. • Reconnaissance : is to identify several feasible routes • Preliminary location survey are used to evaluate the economic & environmental feasibility of the alternatives routes • Final location survey • Preparation of highway plans

  5. Soil Properties • Soil Characteristics: • Origin & formation of soils • Surface texture • Basic Engineering properties of soil • Atterberg limits • Permeability • Shear strength • Classification of soils for Highway use-AASHTO; USCS • Soil Tests for pavement design-Compaction,CBR

  6. Bituminous materials • Description and Uses of bituminous binders- Asphalt cements; SC; RC asphalts, Asphalt emulsion • Properties of asphaltic materials • Consistency • Durability • Rate of curing • Resistance to water action • Tests for asphaltic materials-consistency test; penetration test • Asphaltic concrete is a uniformly mixed combination of bitumen, coarse, fine aggregates & fillers

  7. Traffic Engineering • Spot speed studies- are conducted to estimate the distribution of speeds of vehicle in a stream of traffic at a particular location on a highway • Speed characteristics • Locations of spot speed studies • Methods for conducting spot speed studies • Presentation and Analysis of Spot speed data • Headway- space mean & time mean • Traffic Volume- Different types of traffic counts are carried out, depending on the anticipated use of the data to be collected e.g ADT. AADT • Origin-Destination Study
