This report presents a new method for analysis of the drainage of a saturated base. Starting from basic principles of water retention and flow in porous media, this analysis leads to some new methods for the estimation of minimum degrees of saturation, drainable porosities and drainage times. This study found that current practices in the FHWA subdrainage design manual tend to overestimate the amount of drainage from fine-grained bases and greatly underestimate the amount of drainage from coarse-grained bases. Also of importance is the ability to estimate the lowest degree of saturation that can be achieved through gravity drainage. The new methods for the analysis of pavement subdrainage are implemented in two computer programs: (1) SUBDRAIN - simulates the drainage of water from a pavement base that is initially saturated and provides estimates of the minimum degree of saturation in the field and key drainage times; and (2) SUBDRAIN-C - simulates the flow of water into and out of the base over a period of years - the inputs include a long-term record of 15-minute rainfall data and the output shows how often the base is likely to be saturated or nearly saturated.

SUMMARY This book provides complete coverage of surface and subsurface drainage of all types of pavements for highways, urban roads, parking lots, airports, and container terminals. It provides up-to-date information on the principles and technologies for designing and building drainage systems and examines numerous issues, including maintenance and designing for flood events. Practical considerations and sophisticated analysis, such the use of the finite element method and unsaturated soil mechanics, anisotropy and uncertainties, are presented. This book allows civil engineers to make the best use of their resources to provide cost effective and sustainable pavements. Features Presents a holistic consideration of drainage with respect to pavement performance. Includes numerous practical case studies. Examines flooding and the impacts of climate change. Includes PowerPoint slides which include quizzes, schematics, figures, and tables.

Paper 1: This study covers a condition survey in Indiana of 328.5 mi. of rigid pavements constructed with granular bases. Paper 2: All new concrete pavement in Illinois has been placed on granular subbase where the natural soil is fine-grained and heavy truck traffic is expected. The lower cost of constructing the trenched undrained subbase was a deciding factor in the preference shown for this type of subbase.

Nearly all highway, airport, dock and industrial pavements contain large quantities of untreated aggregate in the form of unbound pavement layers. In many pavements, which are lightly or moderately trafficked, crushed rock or gravel derived aggregates comprise the majority of the construction or, in the case of unsealed pavements, all of the structure. This book provides studies of the performance and description of this material that will help the reader to better understand its characteristics and behaviour both alone and as part of the pavement structure it forms. This work will be useful to practitioners, policy makers, researchers and students. It forms a sequel to the earlier book "Unbound Aggregates in Road Construction" also published by Balkema

This synthesis report will be of interest to pavement design engineers in local, state, and federal transportation agencies. Pavement materials, construction, and maintenance engineers will also find it of interest. In addition, it will be of interest to local technology transfer centers and pavement research engineers. This synthesis describes the state of the practice for thin-surfaced pavement project selection and structural design. It does not establish preferential design criteria (e.g., mix design) nor does it systematically evaluate existing design methods. This report of the Transportation Research Board describes the conditions in which thin-surfaced pavements are considered appropriate, what thin-surfaced pavement types are considered appropriate for given conditions, and the decision criteria used in their selection. Information for the synthesis was collected by surveying state and local transportation agencies and by conducting a literature search, including foreign resources. Case studies and an extensive collection of survey data are presented.
